Opening US President Barack Obama's re-election bid in the city, vice president Joe Biden has blamed the Republicans for growing labour unrest in the country.
Biden voiced a full-throated attack on Republicans and their vision for America as he pushed hard for the nation's educators to support Obama in the 2012 presidential election.
"The new Republican Party has undertaken the most direct assault on labour, not just in my lifetime … but literally since the 1920s," Biden said during the annual meeting of the National Education Association yesterday at McCormick Place here.
"This is not your father's Republican Party. This is a different breed of cat."
"There is an organised effort to place blame for budget shortfalls on educators and other public workers. It is one of the biggest scams in modern American history," Biden said.
Biden's speech to one of the nation's largest teacher's unions came a day before they are expected to decide whether to cast their support to the Obama administration in the election.
The Obama Administration has had sometimes-chilly relations with teachers unions as Obama has pushed an education reform agenda that attempted to pin increased accountability for student performance on teachers.
